System and techniques for enhanced electronic navigation maps for a vehicle are described herein. A descriptor set-up message may be received at a network controller interface (NIC). Here, the descriptor set-up message includes an ethernet frame descriptor. The NIC may then use the ethernet frame descriptor to transmit, across a physical interface of the NIC, multiple ethernet frames, each of which use the same ethernet frame descriptor from the set-up message.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A device for a fixed ethernet frame descriptor, the device comprising: a memory including instructions; and processing circuitry that, when in operation, is configured by the instructions to: receive, at a network controller interface (NIC), a descriptor set-up message, the descriptor set-up message including an ethernet frame descriptor; and transmit, across a physical interface of the NIC, multiple ethernet frames with different payloads, each of the multiple ethernet frames using the ethernet frame descriptor, wherein, to transmit the multiple ethernet frames, the processing circuitry is configured by the instructions to, for each ethernet frame: read data at a memory address specified in the ethernet frame descriptor; and construct the ethernet frame, wherein the ethernet frame descriptor is used to populate a header of the ethernet frame, and wherein the data is used as a payload of the ethernet frame.
2. The device of claim 1 , wherein, to transmit the multiple ethernet frames, the processing circuitry is configured by the instructions to receive packet transmission messages to initiate a read of the data at the memory address.
3. The device of claim 2 , wherein the packet transmission messages are contiguous.
4. The device of claim 1 , wherein the descriptor set-up message includes multiple ethernet frame descriptors, and wherein the multiple ethernet frames are one set of several sets of ethernet frames, each member of the several sets corresponding to one of the multiple ethernet frame descriptors.
5. The device of claim 4 , wherein one of the multiple ethernet frame descriptors is applied to a given ethernet frame according to a schedule provided in the descriptor set-up message.
6. The device of claim 5 , wherein the schedule defines a sequential application of the one of the multiple ethernet frame descriptors.
7. The device of claim 5 , wherein the schedule defines fixed times to apply the one of the multiple ethernet frame descriptors.
8. A method for a fixed ethernet frame descriptor, the method comprising: receiving, at a network controller interface (NIC), a descriptor set-up message, the descriptor set-up message including an ethernet frame descriptor; and transmitting, across a physical interface of the NIC, multiple ethernet frames with different payloads, each of the multiple ethernet frames using the ethernet frame descriptor, wherein transmitting the multiple ethernet frames includes, for each frame: reading data at a memory address specified in the ethernet frame descriptor; and constructing the ethernet frame, including: using the ethernet frame descriptor to populate a header of the ethernet frame; and using the data as a payload of the ethernet frame.
9. The method of claim 8 , wherein transmitting the multiple ethernet frames includes receiving a packet transmission messages to initiate reading the data at the memory address.
10. The method of claim 9 , wherein the packet transmission messages are contiguous.
11. The method of claim 8 , wherein the descriptor set-up message includes multiple ethernet frame descriptors, and wherein the multiple ethernet frames are one set of several sets of ethernet frames, each member of the several sets corresponding to one of the multiple ethernet frame descriptors.
12. The method of claim 11 , wherein one of the multiple ethernet frame descriptors is applied to a given ethernet frame according to a schedule provided in the descriptor set-up message.
13. The method of claim 12 , wherein the schedule defines a sequential application of the one of the multiple ethernet frame descriptors.
14. The method of claim 12 , wherein the schedule defines fixed times to apply the one of the multiple ethernet frame descriptors.
15. At least one non-transitory machine readable medium including information corresponding to instructions for a fixed ethernet frame descriptor, the instructions, when executed by processing circuitry, cause the processing circuitry to perform operations comprising: receiving, at a network controller interface (NIC), a descriptor set-up message, the descriptor set-up message including an ethernet frame descriptor; and transmitting, across a physical interface of the NIC, multiple ethernet frames with different payloads, each of the multiple ethernet frames using the ethernet frame descriptor, wherein transmitting the multiple ethernet frames includes, for each frame: reading data at a memory address specified in the ethernet frame descriptor; and constructing the ethernet frame, including: using the ethernet frame descriptor to populate a header of the ethernet frame; and using the data as a payload of the ethernet frame.
16. The at least one non-transitory machine readable medium of claim 15 , wherein transmitting the multiple ethernet frames includes receiving a packet transmission messages to initiate reading the data at the memory address.
17. The at least one non-transitory machine readable medium of claim 16 , wherein the packet transmission messages are contiguous.
18. The at least one non-transitory machine readable medium of claim 15 , wherein the descriptor set-up message includes multiple ethernet frame descriptors, and wherein the multiple ethernet frames are one set of several sets of ethernet frames, each member of the several sets corresponding to one of the multiple ethernet frame descriptors.
19. The at least one non-transitory machine readable medium of claim 18 , wherein one of the multiple ethernet frame descriptors is applied to a given ethernet frame according to a schedule provided in the descriptor set-up message.
20. The at least one non-transitory machine readable medium of claim 19 , wherein the schedule defines a sequential application of the one of the multiple ethernet frame descriptors.
21. The at least one non-transitory machine readable medium of claim 19 , wherein the schedule defines fixed times to apply the one of the multiple ethernet frame descriptors.
